Monotheism has been defined as the belief in the existence of one god or in the oneness of God.[1] The Oxford Dictionary of the Christian Church gives a more restricted definition: "belief in one personal and transcendent God", as opposed to polytheism and pantheism.[2] A distinction may be made between exclusive monotheism, and both inclusive monotheism and pluriform (panentheistic) monotheism which, while recognising many distinct gods, postulate some underlying unity.[3]

Monotheism is distinguished from henotheism, a religious system in which the believer worships one god without denying that others may worship different gods with equal validity, and monolatrism, the recognition of the existence of many gods but with the consistent worship of only one deity.

According to Judeo-Christian and Islamic tradition, monotheism was the original religion of humanity. This theory was largely abandoned in the 19th century in favour of an evolutionary progression from animism via polytheism to monotheism, but by 1974 this theory was less widely held.[2] Austrian anthropologist Wilhelm Schmidt had postulated an Urmonotheismus, "original" or "primitive monotheism" in the 1910s.[9] It was objected that Judaism, Christianity, and Islam had grown up in opposition to polytheism as had Greek philosophical monotheism.[2] Some writers such as Karen Armstrong believe that the concept of monotheism sees a gradual development out of notions of henotheism (worshiping a single god while accepting the existence or possible existence of other deities) and monolatrism (the recognition of the existence of many gods, but with the consistent worship of only one deity).[citation needed][dubious– discuss]

While all adherents of the Abrahamic religions consider themselves to be monotheists, Judaism does not consider Christianity to be monotheistic, recognizing only Islam as monotheistic.[12] Islam likewise does not recognize modern-day Christianity as monotheistic, primarily due to the Christian doctrine of Trinity, which Islam argues was not a part of the original monotheistic Christianity as preached by Jesus.[13]

Judaism is one of the oldest monotheistic religions in the world.[14] God in Judaism is strictly monotheistic,[15] an absolute one, indivisible, and incomparable being who is the ultimate cause of all existence. The Babylonian Talmud references other, "foreign gods" as non-existent entities to whom humans mistakenly ascribe reality and power.[16]

God, the Cause of all, is one. This does not mean one as in one of a pair, nor one like a species (which encompasses many individuals), nor one as in an object that is made up of many elements, nor as a single simple object that is infinitely divisible. Rather, God is a unity unlike any other possible unity.[17]

Judaism[18] and Islam reject the Christian idea of monotheism. Judaism uses the term shituf to refer to the worship of God in a manner which Judaism does not deem to be monotheistic.

During the 8th century BCE, the worship of YHWH in Israel was in competition with many other cults, described by the Yahwist faction collectively as Baals. The oldest books of the Hebrew Bible reflect this competition, as in the books of Hosea and Nahum, whose authors lament the "apostasy" of the people of Israel, threatening them with the wrath of God if they do not give up their polytheistic cults.[19][20]

Some scholars hypothesize that Judaism was originally a form of monolatrism or henotheism. In this hypothesis both the Kingdom of Israel and the Kingdom of Judah had YHWH as their state god, while also acknowledging the existence of other gods.[21] In this hypothesis, beginning with the fall of Judah to Babylon, when a small circle of priests and scribes gathered around the exiled royal court developed the first idea of YHWH as the sole God of the world.[22]

Shema Yisrael ("Hear, [O] Israel") are the first two words of a section of the Torah, and is the title of a prayer that serves as a centerpiece of the morning and evening Jewish prayer services. The first verse encapsulates the monotheistic essence of Judaism: "Hear, O Israel: the LORD our God, the LORD is one" (Hebrew: שְׁמַע יִשְׂרָאֵל ה' אֱלֹהֵינוּ ה' אֶחָד‎), found in Deuteronomy 6:4, sometimes alternatively translated as "The LORD is our God, the LORD alone." Observant Jews consider the Shema to be the most important part of the prayer service in Judaism, and its twice-daily recitation as a mitzvah (religious commandment). It is traditional for Jews to say the Shema as their last words, and for parents to teach their children to say it before they go to sleep at night.

Christians overwhelmingly assert that monotheism is central to the Christian faith, as the Nicene Creed (and others), which gives the orthodox Christian definition of the Trinity, begins: "I believe in one God". From earlier than the times of the Nicene Creed, 325 CE, various Christian figures advocated[24] the triune mystery-nature of God as a normative profession of faith. According to Roger E. Olson and Christopher Hall, through prayer, meditation, study and practice, the Christian community concluded "that God must exist as both a unity and trinity", codifying this in ecumenical council at the end of the 4th century.[25]

Many modern Christians believe the Godhead is triune, meaning that the three persons of the Trinity are in one union in which each person is also wholly God. They also hold to the doctrine of a man-godChrist Jesus as God incarnate. These Christians also do not believe that one of the three divine figures is God alone and the other two are not but that all three are mysteriously God and one. Other Christian religions, including Unitarian Universalism, Jehovah's Witnesses, Mormonism and others, do not share those views on the Trinity.

Some Christian faiths, such as Mormonism, argue that the Godhead is in fact three separate individuals which include God the Father, His Son Jesus Christ, and the Holy Ghost.[26] Each individual having a distinct purpose in the grand existence of human kind.[27] Furthermore, Mormons believe that before the Council of Nicaea, the predominant belief among many early Christians was that the Godhead was three separate individuals. In support of this view, they cite early Christian examples of belief in subordinationism.[28]

Unitarianism is a theological movement, named for its understanding of God as one person, in direct contrast to Trinitarianism.[29]

In Islam, Allāh (God) is all-powerful and all-knowing, the creator, sustainer, ordainer and judge of the universe.[30][31]God in Islam is strictly singular (tawhid)[32] unique (wahid) and inherently One (ahad), all-merciful and omnipotent.[33] Allāh exists without place[34] and the Qur'an states that "No vision can grasp Him, but His grasp is over all vision. God is above all comprehension, yet is acquainted with all things" (Qur'an 6:103)[31] Allāh is the only God and the same God worshiped in Christianity and Judaism. (29:46).[35]

Islam emerged in the 7th century CE in the context of both Christianity and Judaism, with some thematic elements similar to Gnosticism.[36][37][38][39][40][41][42][43] Islamic belief states that Muhammad did not bring a new religion from God, but is rather the same religion as practiced by Abraham, Moses, David, Jesus and all the other prophets of God.[44] The assertion of Islam is that the message of God had been corrupted, distorted or lost over time and the Quran was sent to Muhammad in order to correct the lost message of the Torah, New Testament and prior scriptures from God.[45]

The Qur'an asserts the existence of a single and absolute truth that transcends the world; a unique and indivisible being who is independent of the creation.[46] The Qur'an rejects binary modes of thinking such as the idea of a duality of God by arguing that both good and evil generate from God's creative act. God is a universal god rather than a local, tribal or parochial one; an absolute who integrates all affirmative values and brooks no evil.[47]

Tawhid constitutes the foremost article of the Muslim profession of faith, "There is no god but God, Muhammad is the messenger of God.[48] To attribute divinity to a created entity is the only unpardonable sin mentioned in the Qur'an.[47] The entirety of the Islamic teaching rests on the principle of tawhid.[49]

As they traditionally profess a concept of monotheism with a singular person as God, Judaism[18] and Islam reject the Christian idea of monotheism. Judaism uses the term Shituf to refer to non-monotheistic ways of worshiping God. Though Muslims believe in Jesus (Isa in Arabic), they do not affirm that he was a begotten son of God. Jesus is mentioned more times in the Qur'an than Muhammad, but never in conjunction with the Christian doctrine of the Trinity (4:171) constituting this to be shirk, deviation from the true Abrahamic religion (2:135), and blasphemous excess in religion. (5:77).

According to the Quran, the Sabians were a monotheistic religious group.[50] Some Hadiths account them as converts to Islam.[51] However this interpretation may be related to the fact that Quraysh polytheists used to describe anyone who converted to Islam with the word "Saba"[citation needed] (صبى/صبوت) which may either mean that this term was used for anyone who changed his religion or that they identified the message of Muhammed as a "Sabian belief". The former linguistic explanation (i.e. saba = changed his religion) is the one adopted by most Muslim scholars.

Sabians are often identified with Mandaeism, a small monotheistic community which lives today in Iraq and call themselves Yahyawiya (Arabic: يحياوية‎‎). Muslim scholars traditionally viewed them as followers of the prophets Noah and Yahya (i.e. John the Baptist).[52]

God in the Bahá'í Faith is taught to be a personal god, too great for humans to fully comprehend. Human primitive understanding of God is achieved through his revelations via his divine intermediary Manifestations.[53][54] In the Bahá'í faith, such Christian doctrines as the Trinity are seen as compromising the Bahá'í view that God is single and has no equal.[55] And the very existence of the Bahá'í Faith is a challenge to the Islamic doctrine of the finality of Muhammad's revelation.[56] God in the Bahá'í Faith communicates to humanity through divine intermediaries, known as Manifestations of God.[57] These Manifestations establish religion in the world.[54] It is through these divine intermediaries that humans can approach God, and through them God brings divine revelation and law.[58]

The Oneness of God is one of the core teachings of the Bahá'í Faith. The obligatory prayers in the Bahá'í Faith involve explicit monotheistic testimony.[59][60] God is the imperishable, uncreated being who is the source of all existence.[61] He is described as "a personal God, unknowable, inaccessible, the source of all Revelation, eternal, omniscient, omnipresent and almighty".[62][63] Although transcendent and inaccessible directly, his image is reflected in his creation. The purpose of creation is for the created to have the capacity to know and love its creator.[64] God communicates his will and purpose to humanity through intermediaries, known as Manifestations of God, who are the prophets and messengers that have founded religions from prehistoric times up to the present day.[57]

Amenhotep IV initially introduced Atenism in Year 5 of his reign (1348/1346 BCE) during the 18th dynasty of the New Kingdom. He raised Aten, once a relatively obscure Egyptian Solar deity representing the disk of the sun, to the status of Supreme God in the Egyptian pantheon.[65] To emphasise the change, Aten's name was written in the cartouche form normally reserved for Pharaohs, an innovation of Atenism. This religious reformation appears to coincide with the proclamation of a Sed festival, a sort of royal jubilee intended to reinforce the Pharaoh's divine powers of kingship. Traditionally held in the thirtieth year of the Pharaoh's reign, this possibly was a festival in honour of Amenhotep III, who some Egyptologists think had a coregency with his son Amenhotep IV of two to twelve years.

Year 5 is believed to mark the beginning of Amenhotep IV's construction of a new capital, Akhetaten (Horizon of the Aten), at the site known today as Amarna. Evidence of this appears on three of the boundary stelae used to mark the boundaries of this new capital. At this time, Amenhotep IV officially changed his name to Akhenaten (Agreeable to Aten) as evidence of his new worship. The date given for the event has been estimated to fall around January 2 of that year. In Year 7 of his reign (1346/1344 BCE), the capital was moved from Thebes to Akhetaten (near modern Amarna), though construction of the city seems to have continued for two more years. In shifting his court from the traditional ceremonial centres Akhenaten was signalling a dramatic transformation in the focus of religious and political power.

The move separated the Pharaoh and his court from the influence of the priesthood and from the traditional centres of worship, but his decree had deeper religious significance too—taken in conjunction with his name change, it is possible that the move to Amarna was also meant as a signal of Akhenaten's symbolic death and rebirth. It may also have coincided with the death of his father and the end of the coregency. In addition to constructing a new capital in honor of Aten, Akhenaten also oversaw the construction of some of the most massive temple complexes in ancient Egypt, including one at Karnak and one at Thebes, close to the old temple of Amun.

In Year 9 (1344/1342 BCE), Akhenaten declared a more radical version of his new religion, declaring Aten not merely the supreme god of the Egyptian pantheon, but the only God of Egypt, with himself as the sole intermediary between the Aten and the Egyptian people. Key features of Atenism included a ban on idols and other images of the Aten, with the exception of a rayed solar disc, in which the rays (commonly depicted ending in hands) appear to represent the unseen spirit of Aten. Aten was addressed by Akhenaten in prayers, such as the Great Hymn to the Aten: "O Sole God beside whom there is none".

The details of Atenist theology are still unclear. The exclusion of all but one god and the prohibition of idols was a radical departure from Egyptian tradition, but most scholars see Akhenaten as a practitioner of monolatry rather than monotheism, as he did not actively deny the existence of other gods; he simply refrained from worshiping any but Aten. It is known that Atenism did not solely attribute divinity to the Aten. Akhenaten continued the cult of the Pharaoh, proclaiming himself the son of Aten and encouraging the Egyptian people to worship him.[66] The Egyptian people were to worship Akhenaten; only Akhenaten and Nefertiti could worship Aten directly.[67]

Under Akhenaten's successors, Egypt reverted to its traditional religion, and Akhenaten himself came to be reviled as a heretic.

The orthodox faith system held by most dynasties of China since at least the Shang Dynasty (1766 BCE) until the modern period centered on the worship of Shangdi (literally "Above Sovereign", generally translated as "God") or Heaven as an omnipotent force.[68] This faith system pre-dated the development of Confucianism and Taoism and the introduction of Buddhism and Christianity. It has features of monotheism in that Heaven is seen as an omnipotent entity, a noncorporeal force with a personalitytranscending the world. From the writings of Confucius in the Analects, it is known Confucius believed that Heaven cannot be deceived, Heaven guides people's lives and maintains a personal relationship with them, and that Heaven gives tasks for people to fulfill in order to teach them of virtues and morality.[68] However, this faith system was not truly monotheistic since other lesser gods and spirits, which varied with locality, were also worshiped along with Shangdi. Still, later variants such as Mohism (470 BC–c.391 BC) approached true monotheism, teaching that the function of lesser gods and ancestral spirits is merely to carry out the will of Shangdi, akin to angels in Abrahamic religions. In Mozi's Will of Heaven (天志), he writes:

"I know Heaven loves men dearly not without reason. Heaven ordered the sun, the moon, and the stars to enlighten and guide them. Heaven ordained the four seasons, Spring, Autumn, Winter, and Summer, to regulate them. Heaven sent down snow, frost, rain, and dew to grow the five grains and flax and silk that so the people could use and enjoy them. Heaven established the hills and rivers, ravines and valleys, and arranged many things to minister to man's good or bring him evil. He appointed the dukes and lords to reward the virtuous and punish the wicked, and to gather metal and wood, birds and beasts, and to engage in cultivating the five grains and flax and silk to provide for the people's food and clothing. This has been so from antiquity to the present."

Worship of Shangdi and Heaven in ancient China includes the erection of shrines, the last and greatest being the Temple of Heaven in Beijing, and the offering of prayers. The ruler of China in every Chinese dynasty would perform annual sacrificial rituals to Shangdi, usually by slaughtering a completely healthy bull as sacrifice. Although its popularity gradually diminished after the advent of Taoism and Buddhism, among other religions, its concepts remained in use throughout the pre-modern period and have been incorporated in later religions in China, including terminology used by early Christians in China. Despite the rising of non-theistic and pantheistic spirituality contributed by Taoism and Buddhism, Shangdi was still praised up until the end of the Qing Dynasty as the last ruler of the Qing declared himself son of heaven.

The Himba people of Namibia practice a form of monotheistic panentheism, and worship the god Mukuru. The deceased ancestors of the Himba and Herero are subservient to him, acting as intermediaries.[69]

The Igbo people practice a form of monotheism called Odinani.[70] Odinani has monotheistic and panentheistic attributes, having a single God as the source of all things. Although a pantheon of spirits exists, these are lesser spirits prevalent in Odinani expressly serving as elements of Chineke (or Chukwu), the supreme being or high god.

In the Proto-Indo-European religion, the supreme god is Dyeus, as the word "Dyeus" is literally used in many Indo-European language cognates to denote a supreme god. However, Proto-Indo-European religion was not monotheistic.

In western Eurasia, the ancient traditions of the Slavic religion had elements of monotheism, of a supreme deity known by many names worshiped by some tribes. The most common name of the supreme deity is Perun and was identified with the Christian God after Christianization.

In speaking of Henotheism, Indo-European religions have had shifting tendencies regarding their supreme god. Consider the ruler of lightning: the supreme god Zeus, Perun, Jupiter controlled lightning himself; while in Norse mythology Odin delegated the power of lightning to his son Thor. In this vein, phenomena controlled by any single henotheistic god differ widely among various Indo-European religions.

Hindu views are broad and range from monism, through pantheism and panentheism (alternatively called monistic theism by some scholars) to monotheism and even atheism. Hinduism cannot be said to be purely polytheistic. Hindu religious leaders have repeatedly stressed that while God's forms are many and the ways to communicate with him are many, God is one.[citation needed] The puja of the murti is a way to communicate with the abstract one god (Brahman) which creates, sustains and dissolves creation.[75]

When Krishna is recognized to be Svayam Bhagavan, it can be understood that this is the belief of Gaudiya Vaishnavism,[80] the Vallabha Sampradaya,[81] and the Nimbarka Sampradaya, where Krishna is accepted to be the source of all other avatars, and the source of Vishnu himself. This belief is drawn primarily "from the famous statement of the Bhagavatam"[82] (1.3.28).[83] A viewpoint differing from this theological concept is the concept of Krishna as an avatar of Narayana or Vishnu. It should be however noted that although it is usual to speak of Vishnu as the source of the avataras, this is only one of the names of the God of Vaishnavism, who is also known as Narayana, Vasudeva and Krishna and behind each of those names there is a divine figure with attributed supremacy in Vaishnavism.[84]

The Nyaya school of Hinduism has made several arguments regarding a monotheistic view. The Naiyanikas have given an argument that such a god can only be one. In the Nyaya Kusumanjali, this is discussed against the proposition of the Mimamsa school that let us assume there were many demigods (devas) and sages (rishis) in the beginning, who wrote the Vedas and created the world. Nyaya says that:

[If they assume such] omniscient beings, those endowed with the various superhuman faculties of assuming infinitesimal size, and so on, and capable of creating everything, then we reply that the law of parsimony bids us assume only one such, namely Him, the adorable Lord. There can be no confidence in a non-eternal and non-omniscient being, and hence it follows that according to the system which rejects God, the tradition of the Veda is simultaneously overthrown; there is no other way open.[citation needed]

In other words, Nyaya says that the polytheist would have to give elaborate proofs for the existence and origin of his several celestial spirits, none of which would be logical, and that it is more logical to assume one eternal, omniscient god.[citation needed]

Sikhi is a monotheistic[92][93] and a revealed religion.[94] God in Sikhi is called Vāhigurū, and is shapeless, timeless, and sightless: niraṅkār, akaal, and alakh. God is present (sarav viāpak) in all of creation. God must be seen from "the inward eye", or the "heart". Sikhi devotees must meditate to progress towards enlightenment, as its rigorous application permits the existence of communication between God and human beings.[95]

Sikhism is a monotheistic faith[96][97] that arose in northern India during the 16th and 17th centuries. Sikhs believe in one, timeless, omnipresent, supreme creator. The opening verse of the Guru Granth Sahib, known as the Mul Mantra, signifies this:

The word "ੴ" ("Ik ōaṅkār") has two components. The first is ੧, the digit "1" in Gurmukhi signifying the singularity of the creator. Together the word means: "One Universal creator God".

It is often said that the 1430 pages of the Guru Granth Sahib are all expansions on the Mul Mantra. Although the Sikhs have many names for God, some derived from Islam and Hinduism, they all refer to the same Supreme Being.

The Sikh holy scriptures refer to the One God who pervades the whole of space and is the creator of all beings in the universe. The following quotation from the Guru Granth Sahib highlights this point:

"Chant, and meditate on the One God, who permeates and pervades the many beings of the whole Universe. God created it, and God spreads through it everywhere. Everywhere I look, I see God. The Perfect Lord is perfectly pervading and permeating the water, the land and the sky; there is no place without Him."

— Guru Granth Sahib, Page 782

However, there is a strong case for arguing that the Guru Granth Sahib teaches monism due to its non-dualistic tendencies:

Sikhs believe that God has been given many names, but they all refer to the One God, VāhiGurū. Sikhs believe that members of other religions such as Islam, Hinduism and Christianity all worship the same God, and the names Allah, Rahim, Karim, Hari, Raam and Paarbrahm are frequently mentioned in the Sikh holy scriptures. Although there is no set reference to God in Sikhism, the most commonly used Sikh reference to God is Akal Purakh (which means "the true immortal") or Waheguru, the Primal Being.

Faravahar (or Ferohar), one of the primary symbols of Zoroastrianism, believed to be the depiction of a Fravashi (guardian spirit)

Zoroastrianism combines cosmogonic dualism and eschatological monotheism which makes it unique among the religions of the world. Zoroastrianism proclaims an evolution through time from dualism to monotheism.[98]

Zoroastrianism is a monotheistic religion,[99] although Zoroastrianism is often regarded[100] as dualistic, duotheistic or bitheistic, for its belief in the hypostatis of the ultimately good Ahura Mazda(creative spirit) and the ultimately evil Angra Mainyu(destructive spirit). Zorastrianism was once one of the largest religions on Earth, as the official religion of the Persian Empire. By some scholars,[who?] the Zoroastrians ("Parsis" or "Zartoshtis") are credited with being some of the first monotheists and having had influence on other world religions. Gathered statistics shows the number of adherents at as many as 3.5 million,[101] with adherents living in many regions, including South Asia.

"The One" (Τὸ Ἕν) is a concept that arises in Platonism, although the writings of Plato himself are polytheistic. The Euthyphro dilemma, for example, is formulated as "Is the pious loved by the gods because it is pious, or is it pious because it is loved by the gods?"

The development of pure (philosophical) monotheism is a product of the Late Antiquity. During the 2nd to 3rd centuries, early Christianity was just one of several competing religious movements advocating monotheism.

A number of oracles of Apollo from Didyma and Clarus, the so-called "theological oracles", dated to the 2nd and 3rd century CE, proclaim that there is only one highest god, of whom the gods of polytheistic religions are mere manifestations or servants.[102] 4th century CE Cyprus had, besides Christianity, an apparently monotheistic cult of Dionysus.[103]

Aristotle's concept of the "Uncaused Cause"—never incorporated into the polytheistic ancient Greek religion—has been used by many exponents of Abrahamic religions to justify their arguments for the existence of the Judeo-Christian-Islamic God of the Abrahamic religions.

The Hypsistarians were a religious group who believed in a most high god, according to Greek documents. Later revisions of this Hellenic religion were adjusted towards Monotheism as it gained consideration among a wider populace. The worship of Zeus as the head-god signaled a trend in the direction of monotheism, with less honour paid to the fragmented powers of the lesser gods.

In Sino-Tibetan and Turco-Mongol traditions, the Supreme God is commonly referred to as the ruler of Heaven, or the Sky Lord granted with omnipotent powers, but it has largely diminished in those regions due to ancestor worship, Taoism's pantheistic views and Buddhism's rejection of a creator God, although Mahayana Buddhism does seem to keep a sense of divinity. On some occasions in the mythology, the Sky Lord as identified as a male has been associated to mate with an Earth Mother, while some traditions kept the omnipotence of the Sky Lord unshared.

Algonquian tribes were/are animists and have numerous spirits and supernatural beings they revere. Most accounts of a single deity called the 'great spirit' were misconceptions of non-Indians designed to modify some aspects of traditional Indian beliefs to befit their monotheistc religion or a step towards converting tribes to Christianity by giving them a conception of a single 'Native American' male deity.
